--- Comment #3 from Jer Noble <jer.noble at apple.com> ---
Yes, it's being worked on. It looks like your test case is hitting a case where it repeatedly tries to seek to t=1.0. The seek completes, but the currentTime is (unexpectedly) < 1.0, so the code tries to seek again. Rinse, repeat.

(Detail: it looks like our AVPlayer periodicTimeObserver is being called with the wrong time after a seek. It's not clear yet whether a WebKit-level workaround exists.)
